Repairing an alternator is usually cheaper than replacing it, but finding the real fault needs a test bench. MSG Equipment offers a range from MS006 to MS008.
When an alternator fails, repairing it is usually cheaper than buying a new one. Typical faults include worn bearings, failed diode bridges or voltage regulators, worn brushes, shorted or broken stator and rotor windings and worn slip rings. Brushes, diode bridges and regulators are the simplest fixes; winding faults are the most labour-intensive and costly.
To pinpoint the faulty component, the alternator should be tested on a bench that recreates its in-car operating conditions. MSG Equipment offers a range for this: the affordable MS006 for any workshop, MS002 COM and MS004 COM that also handle 24V light and medium truck units, and MS005 and MS008 as its most advanced alternator benches.
